Vanderbilt researchers, who helped organize a consortium including the University of Pennsylvania School of Medicine, the University of Miami Miller School of Medicine, and the Boston University School of Medicine, have identified four new genes linked to Alzheimer’s disease. The findings, released today by Nature Genetics, effectively double the number of genes known to contribute to the disease, according to Jonathan Haines, Ph.D., director, Vanderbilt Center for Human Genetics Research.
In the largest study of its kind, researchers from a consortium of 44 universities and research institutions in the United States, including Rush University Medical Center, identified four new genes linked to Alzheimer’s disease. Each gene individually adds to the risk of having this common form of dementia later in life.
Researchers from a consortium that includes Columbia University Medical Center identified four new genes linked to late-onset Alzheimer’s disease, each of which adds to the risk of developing this most common form of the disease. Together they offer a portal into the causes of Alzheimer’s. Their identification will help researchers find ways to determine who is at risk of developing the disease and to identify proteins and pathways for drug development.
Basic Yellow 1, a dye used in neuroscience labs around the world, is a wonder drug for nematode worms. Thioflavin T extended lifespan in healthy worms by more than 50 percent and slowed the disease process in worms bred to mimic aspects of Alzheimer’s. The research could open new ways to intervene in aging and age-related disease.
Researchers at Mount Sinai School of Medicine have found that patients with Alzheimer’s disease have lower glucose utilization in the brain than those with normal cognitive function, and that those decreased levels may be detectable approximately 20 years prior to the first symptoms of Alzheimer’s disease. This new finding could lead to the development of novel therapies to prevent the eventual onset of Alzheimer’s. The study is published online in the journal Translational Neuroscience.
A drug used to treat asthma has been shown to help reduce the formation of amyloid beta, a peptide that is implicated in the development of Alzheimer’s disease, and the subsequent build up of amyloid plaques in the brain by more than 50 percent.
UCLA researchers have identified a new biomarker that could help them track how effectively the immune system is able to clear the brain of amyloid beta, which forms the plaques considered one of the hallmarks of Alzheimer's disease. The pilot study demonstrates how the immune gene MGAT3, which is essential in clearing amyloid beta, is expressed differently in different Alzheimer's patients. The finding may be useful in providing more highly individualized disease prognoses in the future.

The research is published in the March 4th issue of the journal Cell.
Unexpected results from a Scripps Research Institute and ModGene, LLC study could completely alter scientists’ ideas about Alzheimer’s disease—pointing to the liver instead of the brain as the source of the “amyloid” that deposits as brain plaques associated with this devastating condition. The findings could offer a relatively simple approach for Alzheimer’s prevention and treatment.

Mutant presenilin is infamous for its role in the most aggressive form of Alzheimer’s disease—early-onset familial Alzheimer’s—which can strike people as early as their 30s. In their latest study, researchers at the Salk Institute uncovered presenilin’s productive side: It helps embryonic motor neurons navigate the maze of chemical cues that pull, push and hem them in on their way to their proper targets. Without it, budding motor neurons misread their guidance signals and get stuck in the spinal cord.
A quick online assessment tool developed by Johns Hopkins researchers can help worried seniors find out if they are at risk of developing dementia and determine whether they should seek a comprehensive, face-to-face diagnosis from a physician, according to a new study.
Though the cause of Alzheimer’s disease still is unknown, recent studies have implicated three proteins strongly in its onset., amyloid beta, tau, and Fyn. New research from UAB and others indicates that interactions between those three proteins might lead to brain dysfunction and AD in a mouse model of the disease.
The Mediterranean diet, rich in vegetables, fish and olive oil and moderate in wine and alcohol, is associated with slower rates of cognitive decline in older adults, according to researchers at Rush University Medical Center.
Neuroscientists had assumed that a mutation in the progranulin gene, which makes the progranulin protein and supports brain neurons, was sufficient to produce a kind of dementia known as frontotemporal lobar degeneration (FTLD). But now an international team of scientists led by researchers at Mayo Clinic’s campus in Florida have found another genetic factor they say appears to protect against the disorder in progranulin mutation carriers.
With a rapidly expanding population of elders, the number of dementia caregivers in Florida is increasing exponentially. According to the Alzheimer’s Association, nearly 10 million caregivers provide unpaid care to people with Alzheimer’s disease. Finding the best way to support caregivers, especially with fewer state resources available, is one focus of ongoing research at Mayo Clinic in Florida.
People with a known, high risk for Alzheimer’s disease develop abnormal brain function even before the appearance of telltale, amyloid plaques that are characteristic of Alzheimer’s disease, according to a new study from researchers at Washington University School of Medicine in St. Louis. The findings suggest that a gene variant affects brain function long before the brain begins accumulating the amyloid that will eventually lead to dementia.
Neurologists have answered one of the most important questions about Alzheimer's: Do rising brain levels of a plaque-forming substance mean patients are making more of it or that they can no longer clear it as effectively? Researchers found clearance rates decline in Alzheimer's patients.
Many people believe that the popular herb ginseng can improve thinking ability and prevent or even treat dementia. However, a comprehensive review of research failed to find convincing evidence of these benefits.

Can Curry, Wine and Apple Skins Offer an Antidote?
New results from a study by neuroscientists at Rush University Medical Center suggest that people at risk of developing Alzheimer’s disease exhibit a specific structural change in the brain that can be visualized by brain imaging. The findings may help identify those who would most benefit from early intervention.
When a relative experiences memory loss associated with Alzheimer’s disease, holiday gatherings can be trying. Dr. Stephen Moelter, associate professor of psychology at USciences, believes that adults and children can arm themselves with ways to engage people with memory difficulty to ensure a more meaningful holiday season.
Contrary to earlier research, a new, long-term study suggests that cholesterol level in mid-life may not be linked to later development of Alzheimer’s disease, according to a study published in the November 10, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology. However, the results suggest that large decreases in cholesterol levels in old age could be a better predictor of developing the memory-robbing disease.
High cholesterol levels in middle age do not appear to increase women’s risk of developing Alzheimer’s disease and other forms of dementia later in life, new Johns Hopkins-led research finds, despite a body of scientific evidence long suggesting a link between the two.
